+### Minimal EIP1559 gas values
+
+On less crowded networks (such as Sepolia) there may be situations where automatic gas provider will set 
+`maxFeePerGas` & `maxPriorityFeePerGas` near 0 (when empty blocks are mined). To prevent this you can
+set minimal values for them in config:
+
+```
+import "@rumblefishdev/hardhat-kms-signer";
+
+...
+
+const config: HardhatUserConfig = {
+  networks: {
+    ropsten: {
+      url: `https://ropsten.infura.io/v3/${process.env.INFURA_KEY}`,
+      kmsKeyId: "YOUR KMS KEY ID",
+      minMaxFeePerGas: 1600000000,
+      mixMaxPriorityFeePerGas: 1200000000
+    }
+  }
+}
+```
